JOHN B. PROCTOR, 0F BUTLER, INDIANA.

GUN-CLEANER.

Application filed. December 5, 1916.

To all whom it may concern:

Be it known that T, Jenn B. Pnoo'ron, a citizen of the United States, residing at Butler, in the county of Dekalb and State of Indiana, have invented certain new and useful Improvements in Gun-Cleaners, of which the following is a specification.

The invention has for its object to facilitate the cleaning of gun barrels, either straight bored, back bored or choke bored.

A further object is to construct the cleaner so that a chamber will be formed, between the sliding member and the body member of the cleaner, said chamber forming means for retaining a supply of grinding or polishing material when the cleaner is dipped in a mixture of oil and emery, the oil, with the emery therein, being forced outwardly and into engagement with the bore of the gun, when the cleaner is forced into the gun barrel. The outer surfaces of the cleaner memhere being coated by the dipping process, will be further supplied as the cleaner is forced downwardly and upwardly or rotated in the gun barrel, thereby providing efiicient means for removing, lead, rust and any foreign accumulations whatsoever.

A further object is to provide a gun cleaner, having a stationary member adapted to be attached to a gun rod, and a spring actuated member, so constructed that the same will accommodate itself to the curvature of the bore of the gun and have an equal pressure upon said bore for the'entire length of said spring actuated member.

\Vith these and other objects in view the invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size and detail may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings:-

Figure 1 is a perspective view of the guncleaner.

Fig. 2 is a sectional view on line 2-2 of Fig. 1.

Fig. 3 is a sectional view on line 33 of Fig. 2.

Fig. 1 is a sectional view on line 4- 1 of Fig. 2.

Fig. 5 is a sectional view through a gun barrel showing the cleaner therein.

Specification of Letters Patent. Patented Apr. 10 191% Serial No. 135,173.

Fig. 6 is a perspective view of another form of the invention, showing apertures for admitting the oil and emery to the surface of the bore of the gun barrel and means for retaining the oil and emery in the supplv chamber. U

Fig. 7 is a sectional view through a gun barrel and the gun cleaner therein, as illustrated in Fig. 6.

Referring to the drawings 1 designates a body member, its upper part 2 being cylindrical in cross section andhaving a reduced portion 3, for the reception of a ferrule 4, said ferrule being fastened to the reduced portion 3, and the gun rod 5, by means of the pins 6 and 7. The body memher 1 is cut away as at 8, thereby forming the flat surface 9, said body member 1 is also provided with apertures 10, having counter bores 11. Passing through the apertures 10 are the shanks 12 of the screws 13.

The heads 1 lof said screws engage the counter bores 11 thereby forming means for limiting the movement of said screws. The shanks 12 of the screws 13 arethreaded into the member 15, thereby, in connection with the limiting heads 14, in the counter bores 11 providing a radially movable member for contact with the bore of the gun barrel. A pair of springs 16 is disposed between the surface 9 of the body member 1 and the fiat surface 17 of the movable member 15. The springs 16, in one end thereof are provided with apertures 18, for the reception of the shanks 12 of the screws 13, while their other ends are provided with slots 19 which engage pins 20 in the member 1, there being apertures 21 in the member 15, to receive the ends of said pins when the member 15 is forced inwardly, against the action of the springs 16.

To emery or clean the gun barrel 26, the

cleaner is first dipped, preferably in a mixture of oil and emery; this dipping will coat the outer surfaces of the cleaner and also fill the slot 22, between the members 1 and 15. As the cleaner is forced into the barrel, the oil and emery will be forced out of the slot 22, on to the bore of the gun barrel by the forcing of the members together. The cleaner is preferably forced downwardly with a rotary movement, after which a reciprocating movement may be used.

It will be seen, that by the provision of two or a series of springs 16, the pressure of the members against the bore of the gun barrel will be practically uniform at all points of contact.

In Figs. 6 and 7, it will be noted that the member is provided with a plate upon its lower end, said plate overlying the lower end of the member 1, thereby providing means for insuring the flow of oil with the emery therein from the chamber 22, down and on to the bore of the gun barrel. Passages 2'-l and are also provided for conducting the oil and emery from the supply chamber 22, to the surface of the bore of the gun barrel.

If it is desired to emery or clean only a spot in the gun barrel, one side of the cleaner may be dipped in the cleaning material and the grinding action applied to that spot only.

Having thus described my invention what I claim and desire to secure by LettersPatent is 1. A gun-cleaner comprising a body member having its lower end semi-circular in cross section, its upper end being round in cross section and adapted to be secured to a gun rod, a member semi-circular in cross section secured thereto by means of screws having heads en aging counter-bores in the first mentioned member, spring means consisting of a series of springs disposed between said members and normally holding them apart, thereby forming a supply chainber for grinding or polishing material, said springs having apertures in one of their ends through which the shanks of said screws pass, their other ends engaging pins in the body member, and bulged portions on said springs engaging said movable member, thereby providing a uniform pressure upon said movable member throughout its length.

2. A gun-cleaner comprising a body member having its lower end semi-circular in cross section, its upper end adapted to be secured to a gun rod, a radially movable member semi-circular in cross section cured thereto, said members having supply passages from their inner surfaces leading to their peripheries, grooves connecting said aforementioned passages, said members be ing normally held spaced apart by means of a. series of springs, thereby forming a supply chamber t'or grinding or polishing material, means on the lower end of said movable member for preventing downward flowing of the grinding or polishing material except in contact with the bore of the gun barrel and means for limiting the outward movement of said movable member.

In testimony whereof I afiix my signature in the presence of two witnesses.
